<div dir="ltr">So this setup has only stopped working very recently, I've had this setup for almost a year now with probably 100 hours of CS:GO on it.

"Did you try the hyperV clock? it could be a timer issue." (but this didn't fix it for him) Playing in a VM sometimes results in strange timer issues like NPC's and cars spawning after they should have. The issue isn't so much clock drift as it is a jitter, even with the hyperv clock enabled for some reason things don't work properly (but they did work in the past before I changed my OS turning on hyperv clock and enlightenment fixed my timer issues now it doesn't...strange) I imagine that could definitely trigger anti cheat software that looks for things out of place.

I don't know much about CS:GO but I wonder if it might adversely affect game play network data. It might be interesting for you to track those in the VM and sync tightly with NTP. Besides Windows' own NTP client perhaps one might experiment with something like: <a href="http://www.bytefusion.com/products/ntm/ptnt/whatispresentense.htm" rel="noreferrer" target="_blank">http://www.bytefusion.com/products/ntm/ptnt/whatispresentense.htm</a> On 27 Feb 2017, at 17:26, Brandon Ganem wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> I've emailed and attempted to submit tickets.

I've never had this problem occur and have it not solved by a repair, at least it should work long enough to finish your match. It does sound like this is an actual issue with playing in VMs being flagged in the first place though. I just did another 45mins of Valve DM in my VM without issues, I'll keep playing in VM when I play to gather some more info. I call qemu through the CLI, my CPU line is: -cpu host,hv_time,hv_vapic,hv_relaxed,hv_spinlocks=0x1fff, I don't hide KVM. I think we'd probably get better results emailing the VAC and/or CSGO teams than submitting a ticket. We only want to use one instance of the game, so hopefully if they're at least aware of this use case they can keep it in mind during future developments. Or if they fixed the native client that would be nice....
